PCT No. PCT/JP97/02865 Sec. 371 Date Feb. 18, 1999 Sec. 102(e) Date Feb. 18, 1999 PCT Filed Aug. 19, 1997 PCT Pub. No. WO98/08296 PCT Pub. Date Feb. 26, 1998A power unit for creating discharge shock waves, which is excellent in performance, reliability, and durability is provided with: a plurality of capacitors (C1-C6), connected in series; first coils (L1, L2, L3) and switches (S1, S2, S3), which are connected to every other one of the capacitors (C1, C3, C5); first resistors (R11, R12, R13), which are connected in series with the first terminal of a power source (1); second resistors (R21, R22, R23), which are connected in series with the second terminal of the power source (1); and a discharge electrode (2), which is provided on the output side of the last capacitor (C6); wherein each switch (S1, S2, S3) has a first main electrode (a), a second main electrode (b), and a triggering electrode (c). The triggering electrode (c) of a first-stage switch (S1) is connected to a triggering voltage source (3), and the first main electrodes (a) and second main electrodes (b) of the switches (S1, S2), other than the final-stage switch (S3), are respectively connected to second capacitors (C71, C72) and the primary sides (d1, d1) of insulating pulse transformers (T1, T2) via serial electric paths. The triggering electrodes (c) and second main electrodes (b) of the switches (S2, S2) other than the first-stage switch (S1) are connected via the secondary sides (d2, d1) of the insulating pulse transformers (T1, T2).
